[Public health fairs on "environment and human health"--participants, topics, attitudes].

19 meetings dealing with environment and human health, including 7 public hearings related to the planning of an incineration plant and 5 training courses for asthmatic patients, were analysed with regard to participation, persons participating in the discussions, topics covered by the remarks and also emotional involvement and standard of information. There was a total of 835 participants; 1471 "units of statements" were assessed. In the open meetings 18-33% of the participants took part in the discussion, in the closed training sessions the number was 66%. About one-third of the remarks ("units") dealt with the pollution of water, soil and air; a health risk was mentioned in about 20%. The frequency distribution of topics mentioned at the various kinds of meeting is presented. It was surprising that annoyance and anxiety were rarely expressed. The standard of information was classified rather high at the hearings concerned with the incineration of waste, and rather low at the training sessions.
